Here’s another vintage Hamilton film from 1949. This short produced for Hamilton by the Jam Handy Organization was intended as a training video for Hamilton’s sales staff, but served a larger purpose in wider audiences as an educational short as well afterward.
It gives simple and fascinating description of the theory and principle that drives a simple manual mechanical watch in easy-to-understand terms, with some excellent visual aids like a 7 and a half foot working model and a gardenhose-driven mock “clock” to help make the inner workings very clear, even if you have no previous understanding of what makes watches tick.
